Tumon Bay is in the center of the tourist part of the island.
Most of the large hotels are right on the bay.
Because of this, you don’t really see as many fish and coral as you would other places. The coral can often be damaged by tourists.
However, you can still go around and see some nice things.
It’s very shallow, so it’s a good place to go if you have children.
Mostly, you’ll find stag coral and trigger fish. Oh, and a lot of sea cucumbers.
